Very high quality leg warmers. The knitted fabric provides sufficient warmth and breathability over typical spandex (and looks a lot nicer too).
Didn't get that last star as I've had some issue with them slipping. You definitely need bibs/shorts with rubberized grippers with these warmers. I had to hike them up pretty high under my non grabby bib shorts which put lower seam bunch and punch the back of my knee when contracting my lower leg.
